Vega Gateways - DSP Upgrade

DSP Upgrade Procedure

DSP Upgrade Procedure can be achieved via three different ways:

1. DSP Upgrade Via GUI

2. DSP Upgrade Via CLI

3. DSP Upgrade Via AutoExe (automated)

DSP Upgrade Via GUI

The DSP can only be upgraded when required by the Vega firmware, as each Vega firmware is paired with a specific DSP firmware version. 

If a DSP upgrade is necessary, its status will display as FAILED on the Vega's status page, as shown in the screenshot below. 

• To start the upgrade press the Upgrade DSP button

Open

• If the firmware update ZIP package includes multiple DSP files, the Vega gateway will specify which file to upload. In the screenshot below, the Vega gateway requests the file “VEGAIMX_DSP_205401_dgw_3.7.0.bin."

• Select the DSP firmware file and click the Download button to start the upgrade

Open

• Once the upgrade is complete, the Vega gateway will display the screen below and automatically reboot. The device may reboot multiple times during the process

• Once the upgrade is complete, the DSP status will display as ACTIVE, indicating that the DSP is running the correct firmware.

DSP Upgrade Via CLI

DSP firmware can be upgraded via CLI also.

User needs to make sure DSP Firmware bin file i.e. vega_upgrade_X.X.X.bin is present in there respective configured server(ftp/tftp) location/path so VEGA can easily download.

Please find the below set of commands that needs to be triggered on CLI in order to perform DSP Firmware Upgrade:

• set .lan.tftp=x.x.x.x

• upgrade

• download enable

• upgrade dsp

If DSP Upgrade is required, VEGA will generate a WARNING on VEGA CLI to inform user that the DSP Upgrade is Required as illustrated in above image.

If the Upgrade is not successful. VEGA will prompt error message on VEGA CLI for DSP Upgrade Failure reason as shown below:

If Upgrade is successful VEGA will prompt success information over VEGA CLI as shown below:
